http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50435 --- Comment #8 from Ira Rosen 2011-09-18 10:48:43 UTC --- Looks like there is a difference ;) I guess it succeeds with the patch to avoid loop vectorization and the fix of restrict together?

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50413 --- Comment #7 from Ira Rosen 2011-09-18 10:17:12 UTC --- Right. The data-refs analysis fails for the bit assignment, and SLP marks this statement as not vectorizable and continues with the vectorization of other statements, which is incorrect be

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50435 --- Comment #5 from Ira Rosen 2011-09-18 08:52:56 UTC --- Thanks. Data dependence analysis can't determine dependence between src and dst although they have _restrict_, and it works fine on x86_64-suse-linux for example... Does darwin have a kno
